Description

Technical Field

[0001] This utility model relates to the field of motorcycle headlight technology, and more specifically, to a combined headlight with concentrated beam. Background Technology

[0002] In the field of automotive lighting, the performance of headlights plays a crucial role in driving safety. Among them, combination headlights, which can simultaneously meet the needs of high beam and low beam illumination, are widely used in various types of vehicles.

[0003] Currently, there is a critical problem with combination headlights on the market that urgently needs to be solved. In actual use, due to the inherent divergence of the light source and insufficient compatibility between the light guide and the light source, the illumination range of the light source after passing through the light guide cannot achieve an ideal concentrated state.

[0004] When light is transmitted and emitted through a light guide, factors such as the structure and material properties of the guide prevent it from effectively converging and guiding the light. This causes the light, which should be focused on illuminating a specific area, to become significantly dispersed, reducing light utilization efficiency and significantly diminishing the lighting effect. For example, when driving at night, the dispersed light may not provide the driver with a sufficiently far and clear field of vision, increasing driving risks; when there are oncoming vehicles in the opposite lane, the dispersed light may also cause glare interference to other drivers, affecting driving safety.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] Please see Figure 1-8 The present invention provides the following technical solution: Example 1 is to solve the technical problem that the illumination range of the light source is not concentrated after being emitted by the light guide 33 due to the dispersion of the light source and the insufficient adaptability of the light guide 33 during the use of high and low beam lamps.

[0021] The combined headlight includes a lamp cover 1 and a lamp holder 2 located beside the lamp cover 1. It also includes a light guide unit 3 and a quick-release unit 4. The light guide unit 3 is located inside the lamp cover 1. The light guide unit 3 includes a lamp source plate 31, a marker light strip 32, and a light guide cover 33. A pair of lamp source plates 31 are respectively located inside the lamp cover 1. A pair of marker light strips 32 are respectively located beside the lamp cover 1, and both marker light strips 32 are located on both sides of the lamp source plate 31 and close to the inside of the lamp cover 1. A pair of light guide covers 33 are respectively located below the pair of lamp source plates 31, and the end faces of both light guide covers 33 are chamfered convex bevels 331. The quick-release unit 4 is located on the lamp holder 2 and is used to quickly install the light guide unit 3 into the lamp cover 1 and the lamp holder 2.

[0022] In this embodiment, a pair of light guides 33 are configured, each serving to guide the light source and applicable to both high beams and low beams. The lamp source board 31 is used to connect to an external power source and acts as the light source emission point. When the lamp source board 31 is connected to an external power source and activated, it reflects the light source through the light guides 33. The reflected light source is then emitted through the lamp cover 1. When the light emitted by the lamp source board 31 illuminates the chamfered convex slope 331, the angle and surface shape of the chamfered convex slope 331 reflect the light. As the incident light from the light source is reflected on the chamfered convex slope 331, the reflected light propagates according to the direction of the chamfered convex slope 331. After multiple reflections and refractions through multiple chamfered convex slopes 331, the originally dispersed light gradually converges, making the reflected light source more concentrated.

[0023] See Figure 8 The chamfered convex bevels 331 on the end face of each light guide 33 are arranged in a horizontal array.

[0024] In this embodiment, multiple chamfered convex bevels 331 are provided in a raised manner, and the protrusion angle of the chamfered convex bevels 331 relative to the protrusion direction of the lamp holder 2 is preferably set to 30 degrees. This ensures that when the light emitted by the lamp source board 31 shines on the chamfered convex bevels 331, the light will be reflected according to the direction of the chamfered convex bevels 331 of the light guide cover 33.

[0025] See Figure 8 The multiple chamfered convex inclined surfaces 331 on the end face of the light guide cover 33 are spaced apart, and the interval between each chamfered convex inclined surface 331 constitutes a light guide cavity for guiding light.

[0026] The light-guiding chambers between multiple chamfered convex slopes 331 correspond to the high beam and low beam lamps respectively, and these chambers are used to concentrate the light source. The light-guiding chambers further guide and constrain the light reflected by the chamfered convex slopes 331, preventing the light from dispersing again during propagation, thus further enhancing the beam concentration effect. The light source, after reflection and guided by the light-guiding chambers, can be emitted through the lampshade 1, ultimately achieving beam concentration, effectively improving the lighting effect and increasing the illumination distance. By sorting and converging the light entering the chambers, the necessary structural support for the concentration of the light source is provided, ensuring that the light from both the high beam and low beam lamps can be effectively concentrated.

[0027] See Figure 8 The light guide unit 3 also includes a first light guide strip 34; there are multiple light guide strips respectively disposed on the side of the light guide cover 33, and each light guide strip is located on the side of the chamfered convex slope 331, and the multiple light guide strips are arranged in an array along the vertical direction of the chamfered convex slope 331.

[0028] Multiple first light guide strips 34 are arranged on the side of the chamfered convex slope 331 and arrayed vertically. Their function is to collect edge light or scattered light that may appear during reflection from the chamfered convex slope 331 or during propagation in the light guide cavity. After being captured by the first light guide strips 34, these lights will propagate along the guiding direction of the light guide strips and further participate in the beam focusing process, thereby improving the utilization rate and the concentration of the beam.

[0029] See Figure 8 The light guide unit 3 also includes a second light guide strip 35; there are multiple second light guide strips 35 and they are respectively installed below the light guide cover 33, and the multiple second light guide strips 35 are located in the area below the multiple chamfered convex inclined surfaces 331 at intervals.

[0030] Multiple second light guide strips 35 are installed below the light guide cover 33 and in the area below the chamfered convex slope 331 at intervals. Their main function is to collect light that may leak or be insufficiently guided from the area below the light guide cover 33. After being collected by the second light guide strips 35, this light is guided to a suitable light propagation path, ensuring that all light emitted from the lamp source plate 31 can be effectively utilized and participate in the beam focusing process, ultimately emitting a concentrated beam through the lamp cover 1.

[0031] In Example 2, to solve the problem of the installation process of the guide cover and lamp holder 2 and lamp cover 1, that is, the operator needs to hold the guide cover with one hand while the other operator aligns the lamp cover 1 and lamp holder 2 respectively, which leads to the cumbersome process of two operators completing the docking of the first guide mounting plate 41 and the light guide cover 33 before the installation is carried out.

[0032] See Figure 2 , Figure 3 and Figure 6 The quick-release unit 4 includes a first guide mounting plate 41 and a limiting part 42. The first guide mounting plate 41 is slidably disposed on the side of the lamp holder 2, and a first guide abutment groove for abutting the first guide mounting plate 41 is opened on the side of the lamp holder 2. The bottom of the first guide mounting plate 41 is in abutting state with the top end face of the light guide cover 33. When the first guide mounting plate 41 moves toward the lamp holder 2, the end face of the first guide mounting plate 41 can abut with the end face of the first guide abutment groove. The limiting part 42 is disposed on the end face of the first guide mounting plate 41, and the limiting part 42 is used to abut the bottom of the light guide cover 33.

[0033] First, the lamp holder 2 is securely placed on the workbench. Then, the operator places the first guide mounting plate 41 into the first guide abutment groove opened beside the lamp holder 2. After the abutment operation is completed, the operator then abuts the top of the lampshade 1 against the bottom of the first guide mounting plate 41. In this state, the bottom of the lampshade 1 is also abutted and fixed by the limiting part 42. This achieves a quick and accurate installation process of the light guide cover 33 and the first guide mounting plate 41 onto the lamp holder 2, effectively improving installation efficiency and accuracy.

[0034] See Figure 6 The quick-release unit 4 also includes a locking part 43; the locking part 43 has multiple parts and is rotatably disposed at the bottom of the lamp source plate 31, and the multiple locking parts 43 can be screwed in to bring the lamp source plate 31 into contact with the end face of the first guide mounting plate 41.

[0035] After the first guide mounting plate 41 and the light guide cover 33 are installed together, the operator then installs the light source plate 31 on top of the first mounting guide plate. The operator then threads the locking part 43 onto the light source plate 31. After installation, the first guide mounting plate 41 and the light guide cover 33 in the abutting state can be quickly connected after installation.

[0036] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
